The Chatterbox Has Spoken.

Nine girls sat in a sleepover that was reaching the epitome of boredom. They'd lost all conversation starters, gossiped about every celebrity and watched every movie possible. Heather Jackson, a newcomer to the group with a distinctive Irish accent and a very quiet and mysterious personality suggests they play with her chatterbox which she conveniently had with her...

Her chatterbox is very strange and doesn't have any good things in it, instead predicts the death of six out of all the girls, saying it will take place some time the following year.

That night there was a fatal fire in which one girl died, one girl fled and seven mourned.

Just one year later, one in their group dies just as the chatterbox had predicted. They don't take notice yet until the second girl dies and they remember the chatterbox. It's up to them to try and prevent the remaining deaths. One by one girls are dying. All the same as the chatterbox has said.
